Secret Wonders is a set in the Diamond & Pearl series. It was released on November 1, 2007. The printed size is 132, and the checklist is the same length. Mew is 15/132, in position 15 of 132 on this checklist. Before it is 14 Lugia, and after it is 16 Raikou. The listed rarity is Rare Holo.
Mew is a Basic Psychic Pokémon with 60 HP. The card lists level 40. In the Pokédex this is Mew (#151), generation 1 (Kanto).
Kagemaru Himeno illustrated this card. The same name is on 656 other cards in the catalog.
Mew (#151) has 60 other cards in the catalog. Those other cards are in 34 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Mew 8/53 in Wizards Black Star Promos (1999). That card lists 50 HP, and this one lists 60 HP. The rarity there is Promo, and here it is Rare Holo. Ken Sugimori illustrated that card, and Kagemaru Himeno illustrated this one. 47 other cards of Mew list a different HP.
The attack Psychic Balance lists no damage number. If you have less cards in your hand than your opponent, draw cards until you have the same number of cards as your opponent. (If you have more or the same number of cards in your hand as your opponent, this attack does nothing.) Re-creation is another attack lists no damage number. The cost is Psychic, Colorless, Colorless. Choose an attack on 1 of your opponent's Pokémon in his or her discard pile. Re-creation copies that attack except for its Energy cost. (You must still do anything else required for that attack.) Mew performs that attack. Weakness is Psychic +20. Retreat cost is 1. The flavor text reads "Because it can use all kinds of moves, many scientists believe MEW to be the ancestor of Pokémon."
I keep a set binder for Secret Wonders, meant to hold every card of that set. This card is one slot in the Secret Wonders set binder. A generation binder holds one card of each species. Mew can fill a slot in Generation 1 binder (Kanto). I still need this card.
